Case Description

Summary based on the NamUs case record (MP23328) and 11 other sources
Andreas Marts, a 25-year-old from Leavenworth, Kansas, was last seen on July 16, 2010. Marts, who suffered from schizophrenia and Parry-Romberg Syndrome (a condition that causes facial tissue degeneration), had recently been released from the hospital. At the time of his disappearance, he was described as being highly agitated and delusional, telling his family that he intended to "cleanse himself in the river for God."

Shortly after his disappearance, his car, shoes, and wallet were found near the boat ramp at Riverfront Park in Leavenworth, close to the Missouri River. During that period, the river was at a historic high, having washed away several encampments and caused numerous fatalities. This led authorities to believe that Marts may have entered the river, though his body was never recovered. The circumstances suggest that he may have drowned, but his case remains unsolved.

Marts had undergone multiple reconstructive surgeries due to his condition, and he had several medical implants in his face, making his disappearance even more complex. Despite searches and investigations, no further clues about his fate have emerged. His family continues to seek answers.
